South African manufacturing companies need to develop similar levels of sophistication and expertise in the automation industry as its international rivals, to compete for these markets and meet rising consumer expectations. To remain competitive, these manufacturing companies must manage their plants extremely efficiently to ensure the quality of assembled products; allow for rapid product introduction and product changes; achieve shortened throughput cycles; ensure more reliable delivery dates; and effectively coordinate product demand while contending with decreased product lifespans. To accomplish this, manufacturing companies in SA are progressively engaging in the current trend in automation known as reconfigurable manufacturing. Due to the extreme flexibility of these reconfigurable systems, the monitor and control systems for these require the same levels of flexibility. The purpose of the study is to develop a hybrid control and monitoring system, to supervise and control reconfigurable assembly systems (RAS), and adapt to the flexibility of these systems. To achieve this, a literature study was done in the research area to reveal the prerequisites for such systems; the physical assembly devices were designed and built; the separate software modules developed and ultimately integrated into the intended system. The tests to validate the system were developed in such a way that each subsection of the system is validated by using a different system software function. This inevitably confirms the functionality of the fundamental components and the system in entirety. The results indicated that devices are easily added to the system; devices are successfully detected and identified; how the system plans production, and how the system automatically configures itself. Further results showed the capability of the system to generate and virtually wire system runtime code; store and retrieve production data; as well as warn and alarm on unwanted conditions. By obtaining these results, companies can configure their systems with ease, in a shorter amount of time, and without any human error. Moreover, their systems will be more flexible, allow easy addition of new products and assembly devices, and with minimal downtime. This will enable SA manufacturing companies to be more competitive, ensure increased productivity, achieve extreme system flexibility, and decrease lead times – thus ensuring them an advantage over their international competitors.

This book was released on 2016 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assembly system at the Research Group in Evolvable Manufacturing System (RGEMS) is designed to assemble products part by part and also ensuring good quality products. This system uses different kinds of industrial devices that are integrated in a way that the devices are dependent on each other in order to work properly on a production cycle. The disadvantage of systems of this nature is that if one of the devices malfunctions and is not attended to, the production line will get affected, which will cost time and money. In order to ensure that malfunctioning of devices is acknowledged in time, the system devices must be monitored while busy in progress; this is normally done by a system operator who uses a computer and checks if there is any change in system data using a Supervisory Control and Data Acquisition (SCADA) system. This is, however, inconvenient in that the system operator can only monitor and control the system when connected to the system’s network. Today we live in a wireless world, where anything can be accessible from anywhere in the world; internet and web technologies made all this possible. It was therefore proposed to design a system that can monitor and control the assembly system from a remote location. This system uses OLE Process Control (OPC) technology and web technology in order to read and write data to the system from the OPC server through the internet. This data is presented on a web user interface where it is viewed as analogue or digital data. The user only needs the internet browser installed to his/her computer or smart phone and also to be authorized by the system administrator in order to be able to monitor and control the system.

This book was released on 2021-08-17 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book illustrates the main characteristics, challenges and optimisation requirements of robotic disassembly. It provides a comprehensive insight on two crucial optimisation problems in the areas of robotic disassembly through a group of unified mathematical models. The online and offline optimisation of the operational sequence to dismantle a product, for example, is represented with a list of conflicting objectives and constraints. It allows the decision maker and the robots to match the situation automatically and efficiently. To identify a generic solution under different circumstances, classical metaheuristics that can be used for the optimisation of robotic disassembly are introduced in detail. A flexible framework is then presented to implement existing metaheuristics for sequence planning and line balancing in the circumstance of robotic disassembly. Optimisation of Robotic Disassembly for Remanufacturing provides practical case studies on typical product instances to help practitioners design efficient robotic disassembly with minimal manual operation, and offers comparisons of the state-of-the-art metaheuristics on solving the key optimisation problems. Therefore, it will be of interest to engineers, researchers, and postgraduate students in the area of remanufacturing.

This book was released on 2007-06-08 with total page 763 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dear reader! In your hand you have the second book from the series “XXI Century Techno- gies. ” The first book under the title “Manufacturing Technologies for Machines of the Future” was published by “Springer” in 2003. This book is aimed at solving one of the basic problems in the development of modern machine-building – working out of technologies and manufacturing equipment which would promote the continuous development and improvement of the final product design, rapidly “adaptable” to the requirements of the market as for the quantity, quality, and variety of products manufactured with the lowest cost and minimum time and labor of the product process. In this book the problems of theory and practice of development in the reconfigurable manufacturing systems and transformable factories for various machine-building branches with a focus on automotive industry are discussed. The problems concerning the development of a new class of production systems which in comparison to the flexible manufact- ing systems are composed of a far less quantity of machine-tools (reduced cost of production) are discussed. In comparison to the conventional automated lines (dedicated systems) they make it possible to rapidly transform the equipment for new products manufacturing. The book has some advantages concerning the art of scientific ideas and the presentation of developments.

Available in PDF, EPUB and Kindle. Book excerpt: The technologies for product assembly and manufacturing evolve along with the advancement of enabling technologies such as material science, robotics, machine intelligence as well as information and communication. Furthermore, they may be subject to fundamental changes due to the shift in key product features and/or - gineering requirements. The enabling technologies emerging offer new opportunities for moving up the level of automation, optimization and reliability in product assembly and ma- facturing beyond what have been possible. We see assembly and manufacturing becoming more Intelligent with the perception-driven robotic autonomy, more flexible with the human-robot coupled collaboration in work cells, and more in- grated in scale and complexity under the distributed and networked frameworks. On the other hand, the shift in key product features and engineering requirements dictates the new technologies and tools for assembly and manufacturing to be - veloped. This may be exemplified by a high complexity of micro/nano system products integrated and packaged in 3D with various heterogeneous parts, com- nents, and interconnections, including electrical, optical, mechanical as well as fluidic means.

Available in PDF, EPUB and Kindle. Book excerpt: In the last decade, the production of mechanical components to be assembled in final products produced in high volumes (e.g. cars, mopeds, industrial vehicles, etc.) has undergone deep changes due to the overall modifications in the way companies compete. Companies must consider competitive factors such as short lead times, tight product tolerances, frequent market changes and cost reduction. Anyway, companies often have to define production objectives as trade-offs among these critical factors since it can be difficult to improve all of them. Even if system flexibility is often considered a fundamental requirement for firms, it is not always a desirable characteristic of a system because it requires relevant investment cost which can jeopardize the profitability of the firm. Dedicated systems are not able to adapt to changes of the product characteristics while flexible systems offer more flexibility than what is needed, thus increasing investment and operative costs. Production contexts characterized by mid to high demand volume of well identified families of products in continuous evolution do not require the highest level of flexibility; therefore, manufacturing system flexibility must be rationalized and it is necessary to find out the best trade-off between productivity and flexibility by designing manufacturing systems endowed with the right level of flexibility required by the production problem. This new class of production systems can be named Focused Flexibility Manufacturing Systems-FFMSs. The flexibility degree in FFMSs is related to their ability to cope with volume, mix and technological changes, and it must take into account both present and future changes. The required level of system flexibility impacts on the architecture of the system and the explicit design of flexibility often leads to hybrid systems, i.e. automated integrated systems in which parts can be processed by both general purpose and dedicated machines. This is a key issue of FFMSs and results from the matching of flexibility and productivity that respectively characterize FMSs and Dedicated Manufacturing Systems (DMSs). The market share of the EU in the machine tool sector is 44%; the introduction of focused flexibility would be particularly important for machine tool builders whose competitive advantage is based on the ability of customizing their systems on the basis of needs of their customers. In fact, even if current production contexts frequently present situations which would fit well with the FFMS approach, tradition and know-how of machine tool builders play a crucial role. Firms often agree with the focused flexibility vision, nevertheless they decide not to pay the risk and efforts related to the design of this new system architecture. This is due also to the lack of well-structured design approaches which can help machine tool builders to configure innovative systems. Therefore, the FFMS topic is studied through the book chapters following a shared mission: "To define methodologies and tools to design production systems with a minimum level of flexibility needed to face, during their lifecycle, the product and process evolution both in the technological and demand aspects. The goal is to find out the optimal trade-off between flexibility and productivity". The book framework follows the architecture which has been developed to address the FFMS Design problem. This architecture is both broad and detailed, since it pays attention to all the relevant levels in a firm hierarchy which are involved in the system design. Moreover, the architecture is innovative because it models both the point of view of the machine tool builder and the point of view of the system user. The architecture starts analyzing Manufacturing Strategy issues and generating the possible demand scenario to be faced. Technological aspects play a key role while solving process plan problems for the products in the part family. Strategic and technological data becomes input when a machine tool builder performs system configuration. The resulting system configurations are possible solutions that a system user considers when planning its system capacity. All the steps of the architecture are deeply studied, developing methods and tools to address each subproblem. Particular attention is paid to the methodologies adopted to face the different subproblems: mathematical programming, stochastic programming, simulation techniques and inverse kinematics have been used. The whole architecture provides a general approach to implement the right degree of flexibility and it allows to study how different aspects and decisions taken in a firm impact on each other. The work presented in the book is innovative because it gives links among different research fields, such as Manufacturing Strategy, Process Plan, System Design, Capacity Planning and Performance Evaluation; moreover, it helps to formalize and rationalize a critical area such as manufacturing system flexibility. The addressed problem is relevant at an academic level but, also, at an industrial level. A great deal of industrial sectors need to address the problem of designing systems with the right degree of flexibility; for instance, automotive, white goods, electrical and electronic goods industries, etc. Attention to industrial issues is confirmed by empirical studies and real case analyses which are presented within the book chapters.
